turbo fuel maps
 

I've been having an issue with getting drivability improved on the Z28tt, and was wondering how your fuel/timing/accel enrichment was programmed. I've already increased the MAP enrichment from 10% to 22%, and still get a lean pop on stabs of the throttle. The TPS enrichment is at 4ms asyc pulsewidth (adds 4ms of fuel to the base pulse), so I guess I should bump that up too... FWIW, the package is 399 cid, AFR210's, Pro-ram single plane intake, gale banks tt manifolds, T04e's, and 2.5" downpipes.

what kind of dfi? on my f.a.s.t. system it is pretty easy to tune with a dyno. what system do you have? it shouldnt be hard with some dyno time and good o'2's

It's a DFI Gen 6. I added pulsewidth to the TPS table, and all is well now. WOT was good, so the dyno will come later when I start optimizing the timing tables at WOT.
